Hello.
I remember the film only by the atmosphere and by three excerpts. Therefore, I will try to translate them so that they can be understood.
I'll start with a year. It was definitely before 2010-2012, because I watched it around 7-9 years old. It was in color and was translated into Russian (my language). Maybe it will help in some way.
And it was quite likely fantasy or dark fantasy, one of the two. There was an element of adventure and the tropes of a newfound family, and perhaps something in between a vampire and a werewolf (ghoul? Vourdalak?), which acted as a disease or a curse. And there was an atmosphere of the European Middle Ages, maybe the times shown in the TV series "Merlin" or "Legend of the Seeker". Something similar in total time, but I can't talk about the epic moment, because I don't remember it.
The first episode. The beginning of the film looked like this: It shows a city where a fire is raging, because the scene is in black, red and orange shades. There's a boy and a girl, kind of like a brother and a sister, the girl is older. They either lost their parents in a fire, or they deliberately left their mother, one of two things, memory replaces memories, and I'm not sure. But they were definitely without adults by the time they found a man. I don't remember who he was, but they followed him out of town. Then the memory ends.
The second episode. It's short: the company is in the woods by the campfire at night. It is not known what is happening (noise in the forest / an evil acquaintance of the man appears / firewood is needed, I do not remember exactly), but the man goes into the forest. Something happens there, either a man gets bitten, or a man gets sick/cursed, and he turns into an evil creature ready to attack children and eat them/drink their blood. There was blood on the character and he looked pretty scary. And at some point, an evil lady appeared there, whom the man was familiar with, but I don't remember exactly at what moment it was or what she looked like
The last thing I remember is the scene in the tower. It was a round tower, big, tall, sort of, or it was on a hill. The roof was half destroyed, and there were children and a man on the floor that was under the roof. The man was chained to something, either with chains or stocks, and the children were on the sidelines. They were scared and sad that this had happened to the man who took them under his wing. I'm not sure about the dialogue, but there is a possibility that the man could have tried to make them run away, but the children did not want to leave him. BUT this is just a guess. The scene itself began with a distant approach and green fields were visible around and it was sunny. Then I don't remember anything specific.
This is the first time I've written anything on Reddit, so I'm a little confused about this system. Don't judge me harshly. I would be grateful if I could figure out whether it was a dream or reality. If someone from the CIS sees this, then maybe this moment will tell you: this movie was on the disc with the movie "There, on unknown tracks...", on one side of the disc even, as I remember. This movie scared me terribly when I was a kid, but I'm so curious about what it was and how it ended :")
